An optical laminate is provided. When the optical laminate is applied to an OLED display device, the problem of visibility due to reflection of external incident natural light of the device can be solved, and simultaneously its display quality can also be improved.

The circular polarizer may be omitted from a display to increase efficiency. A polarizer-free display may use other non-polarizer techniques to mitigate reflections of ambient light and mitigate diffraction reflection artifacts. The polarizer-free display may include a black pixel definition layer that absorbs ambient light. Color filter elements may be included in a black matrix to mitigate ambient light reflections. An intra-anode phase shift layer and/or an inter-anode phase shift layer may be included in the display to mitigate diffractive reflection artifacts. Multiple sub-pixels of the same color may be used in a single pixel to ensure a neutral reflection color. The display may include a cathode layer that is patterned to have openings over the black pixel definition layer to mitigate reflections. The display may include diffusive particles (in the color filter element or in a separate diffuser layer) to mitigate diffractive reflection artifacts.

A light-emitting structure includes a substrate, a sub-pixel stack over a surface of the substrate, and a bank including a first bank portion and a second bank portion. The sub-pixel stack has an emissive stack including an emissive layer between a first transport layer and a second transport layer, a first electrode layer coupled to the first transport layer, and a second electrode layer coupled to the second transport layer. The second bank portion is between the first bank portion and the sub-pixel stack, and the bank surrounding at least the emissive stack and the first electrode layer forms an interior space above the sub-pixel stack.

A display device includes a display substrate, a light emitting element layer disposed on a surface of the display substrate and including display pixels, a sensing substrate having a surface attached to another surface of the display substrate, a sensing element layer disposed on another surface of the sensing substrate and including sending pixels that each sense light of a color, and a photorefractive layer disposed on the sensing element layer and including micro lenses.
